Described herein is an arrangement () for guiding a wire in a wire binding machine (), wherein the arrangement () comprises a guide member () and a first spring () arranged to act with a first spring force against the guide member (), wherein the guide member () is arranged to bear against the wire and act against the wire with said first spring force in order to guide the wire during a wire binding process when the wire moves relative to the guide member (). The guide member () is arranged so that a movement of the guide member () substantially away from the wire is allowed in order to reduce friction forces between the guide member () and the wire during the wire binding process, so that locking of the wire against the guide member () is prevented. Also described herein is a wire binding machine () comprising an arrangement ().

A breaker machine includes a power source, a tool holder arranged to receive a tool and a power driven striking mechanism arranged to strike a tip of the tool with a striking frequency on a hard surface. The breaker machine further includes control circuitry arranged to control an output from the power source and load detection means arranged to detect the load of the power source and transmit information relating to the detected load of the power source to the control circuitry. The control circuitry is arranged to receive information relating to a load of the power source, select a striking frequency based on the information relating to the load of the power source and to apply the selected striking frequency by ramping a current striking frequency to the selected striking frequency based on a predetermined ramping scheme by controlling the output from the power source.

A knot plate () for a tying machine () is described. The knot plate () is designed as a substantially circular disc, wherein the knot plate () comprises: an aperture () arranged substantially in the middle of the knot plate (), wherein the aperture () comprises a substantially circular form, and two through slots () for receiving of a binding wire () arranged in the knot plate () substantially on opposite sides of each other in relation to the aperture (). The knot plate () comprises two grooves () for receiving the binding wire, wherein each of the two grooves () connects one respective through slot () of the two through slots () with the aperture (), each of the two grooves () ends in the aperture () in a direction that coincides with substantially tangential directions of the aperture () so that initially the binding wire substantially follows a wall of the substantially circular formed aperture (). A tying machine () comprising a knot plate () is also described.

An arrangement arranged to enclose a circuit board comprising electronic components is described. The arrangement comprises a structure designed to receive the circuit board and the electronic components, a housing designed to receive the structure, a cover designed to be connected to the housing, and an electric socket adapted to provide the circuit board with electricity. The electric socket is comprised in at least one of the housing or the cover. The arrangement is arranged to enclose the circuit board by the housing and the cover, wherein the structure is designed to be releasable and at least partly bear against the circuit board and the electronic components. A tool comprising an arrangement is also described.

An arrangement for feeding at least a part of a drilling machine in at least a first direction. A drilling system and a method are provided. The arrangement includes a first end portion, a second end portion, an outer cylinder, a piston and a piston rod. The piston and the piston rod are displaceably arranged in the outer cylinder such that the piston and the piston rod, the outer cylinder and the end portions delimits a first chamber and a second chamber for a pressure medium in the outer cylinder on a respective side of the piston. A valve is connected to the first chamber for reducing the pressure medium in the first chamber. The valve is arranged to be opened at an increased pressure in the second chamber.

A rock drill machine with a feed leg. The feed leg is attached to the rock drill machine with one end and rests on a support with another end. The feed leg is configured to feed the rock drill machine in a drilling direction and to interrupt feeding of the rock drill machine in the drilling direction. A control regulates the feed leg and a starter activates the rock drill machine. The control is provided on a rear handle in close proximity to the starter such that the control and the starter can be reached at the same time with one hand. Hereby, it is possible, with one hand, to activate and interrupt activation of the rock drill machine respectively, and simultaneously regulate the feed leg to feed the rock drill machine in the drilling direction and interrupt the feeding of the rock drill machine in the drilling direction.

A separate hydraulic power pack for providing at least one user with an oil flow. The hydraulic unit includes a motor, a hydraulic pump driven by the motor, a tank, an oil inlet, an oil outlet, a heat exchanger, and a first conduit system for oil. The first conduit system connects at least the oil inlet, the heat exchanger, the oil tank, the hydraulic pump and the oil outlet. The heat exchanger is provided for liquid cooling of the oil. A cooling liquid inlet for connection to a cooling liquid source, a first cooling liquid outlet and a second conduit system for a cooling liquid.
